Welded PVC aerators to fit onto concrete slab for single ply membranes.

Welded PVC aerators to fit onto concrete slab for single ply membranes.

Tough and durable vent, designed to help aerate concrete slabs and allow the structure to breathe.

Features and benefits:

• It draws moisture away from a concrete slab and is placed onto the bare concrete beneath the waterproofing membrane and insulation.
• Bonded by using hot air gun (not direct contact to a flame).
• The membrane is welded to the top of the base of the vent, creating a flue which helps to draw vapour out of the concrete.
• There are a series of ribs along the underside of the round base plate which encourage the movement of vapour along the base and into the flue and also act to alleviate any hot air which might appear between the slab and the membrane.
• The top of the flue has three lateral holes to allow the vapour to escape into the atmosphere.
• It is covered by a hood which overlaps the internal holes, preventing rainwater entering the system but still allowing the passage of vapour.
